Lion cubs encounter adult males for the first time at Australian Zoo

Keepers at Monarto Safari Park in Australia celebrated after four of the zoo's lion cubs were welcomed into the resident pride with a successful meeting between the youngsters and three adult males.

In video shared this week, the zoo announced the face-to-face encounter between the cubs and the 'big boys' was a success, allowing the three large males, the four cubs and three lionesses to live as one pride.

"In the wild, interactions between males and cubs can sometimes be less than friendly so it's incredible to have the cubs and our three boys mixing so brilliantly," the zoo's carnivore keeper, Christy Tonkin, said.
